Set node.netboot to False for allocated nodes.

[Gavin Panella (allenap)]

I could have sworn we'd already fixed this! Anyway, cool.

I'm not entirely happy with this because it's possible to have allocated nodes
that need netboot=True if they have not started and finished installing.

Didn't we discuss changing the existing migration so the field defaults to
False? People that have already applied the migration won't care as they
already have a problem that needs fixing in a different way.

I think the consensus was that it was better to accidentally set netboot to True (with this migration) to an installing node than to set netboot to False (with migration number 10) on a deployed node. Also, a very good point was made: it's pretty improbable that one would want to upgrade the package while installing a node.

I think changing the default value in the migration would be more dangerous.

We need another migration because, like you said, people who have already applied migration 10 need another migration.

Now, I've got a question for you: do we want to backport this to 1.2? This is a bit tricky because, as you know, migrations must be applied in order so this means we will have to back all the migrations (I think there is 6 or 7 of them). But migrations should be pretty isolated (tiny model change + migration) so it's doable.

I am confused. This migration is setting allocated nodes to False. Or
is that what you meant?

I was actually implying that we don't need to worry about the people who
already applied it, since they will have needed to fix their data already.

For people who have not applied it yet, why do you think it would be
dangerous to do this?

No I don't think so - same reason. Plus, it's tricky as you say.

Sorry, I got mixed up. What I wanted to say is that we thought it would be less problematic to set netboot to False by accident (with this migration) on an installing node rather than to keep it the way it is now (when an installed node can have its netboot set to True by migration #10).

For people who have applied the migration, there is little we can do (apart from backporting all the migrations up to the new one).

Like you said, fixing the migration #10 (with code similar to the one in this branch) could help people who haven't applied the migration yet. That fix could be backported to 1.2 and 1.3.

Right - assuming an upgrade is not done when a node is installing. It's
coming back to me now :) (Sorry, Lyme brain)

Right so this is my theory - people who've not applied the migration yet would
benefit from us fixing the migration. People who *have* applied it won't
benefit from anything we do, it needs admin action to re-install the node or
DB surgery.

Yes, so the summary is:
- The situation of the people who have run migration #10 but haven't rebooted a node yet will be solved by this migration (migration #56).
- People who have run migration #10 and want to reboot an allocated node need to fix the netboot param themselves.
- The situation of the people who haven't run migration #10 will be solved by the upcoming fix I'll do to migration #10. That fix can be backported to 1.2 and 1.3.

All good Julian? (Your vote "Needs info" is still set.)
